HUIZENGA, Jan Marten; SILBERBAUER, Michael; DENNIS, Rainier  e  DENNIS, Ingrid. An inorganic water chemistry dataset (1972-2011) of rivers, dams and lakes in South Africa. Water SA [online]. 2013, vol.39, n.2, pp.335-340. ISSN 1816-7950.

A national dataset of inorganic chemical data of surface waters (rivers, lakes, and dams) in South Africa is presented and made freely available. The dataset comprises more than 500 000 complete water analyses from 1972 up to 2011, collected from more than 2 000 sample monitoring stations in South Africa. The dataset includes the major ion chemical composition and numerous calculated variables that can, amongst others, be used to determine accuracy of the analysis. The methods described here have potential for improving quality control measures in water chemistry laboratories by detecting anomalous samples. The processed data are available in Excel spreadsheets and can be downloaded from the website of the Centre for Water Science and Management based at the North-West University (www.waterscience.co.za/waterchemistry/data.html).

Palavras-chave : national data set; inorganic water chemistry; South Africa; surface waters.
